After using Photo Story 3 successfully for many years with XP, I downloaded the latest version from Microsoft Photo Story 3 download site onto new PC running Windows 7 Home Premium. No problems with download, however the motion customisation frame for any image does not respond to dragging by the mouse. I have tried both 16bit and 32 bit monitor resolutions and also the "Troubleshoot Compatibilty" feature associated with the .msi install file but with no success. Can anyone assist please? Many thanks.
